I have very bad, big blackheads on my nose and around my nose. I bought this one to help me reduce them. Of course I did know this will not make miracle after the first use but still, I had some hope. In the first and second time it didn't remove any blackheads just made my skin smoother. Sadly when I used this at the third time, the product's surface has changed. It became very harsh. Now it just irritates my skin even I use gently. :(
